A two dead bolt door lock is disclosed wherein the bolts are transversely disposed and wherein the bolts are disposed one behind the other in the locked position so as to provide a secure locking mode. When door mounted, and in the locked position, a vertical bolt is disposed on the inside of the door adjacent the jamb and a horizontal bolt is mounted in the jamb. Attempts to jimmy the horizontal bolt in its line of least resistance are frustrated by the presence of the vertically locked bolt acting against the jimmying force. The locks are both operated by a single key actuated cylinder and/or hand knob through a common connection rod with coordinated cam actions. In another embodiment, keys may be employed on both the inside and the outside of the door.
